Dialysis is a popular technique used for the exchange of buffer medium across semi-permeable membranes. Dialysis devices are available in many configurations for research applications. We offer innovative dialysis devices and accessories for processing small samples. The Tube-O-DIALYZER mini dialysis system is designed for small sample volumes of 20mul to 2.5ml.The Tube-O-DIALYZER tube comes in two ideal sizes the Micro unit allows efficient dialysis of 20-250mul samples and the Medi unit is optimized for samples between 0.2-2.5ml. Both sizes are available with membranes with molecular weight cutoffs (MWCO) of 1k 4k 8k 15k and 50k Daltons.Tube-O-DIALYZER comes in packs of 20 each supplied with 6 appropriately sized floats and storage caps to allow storage of dialyzed samples. for added convenience Tube-O-DIALYZER is also available as a mixed kit containing 10 Micro and 10 Medi units.
